eye lens
Low-mediumTechnical/Medical (primary); can be formal in general usage.
Definition
Meaning
The transparent, curved structure in the eye that focuses light onto the retina, enabling clear vision.
Can refer to an artificial intraocular lens implanted during cataract surgery, or, in broader non-technical usage, simply to a person's lens. In some contexts (photography, optics), the term can be extended to mean a lens that mimics or relates to the function of the eye's natural lens.
Linguistics
Semantic Notes
This is a compound noun (noun+noun). 'Eye' functions as a modifier specifying the type of lens. It can be parsed as either [eye lens] or [eye] [lens], but is most commonly treated as a single lexical unit in medical/optical contexts.

Conceptual Metaphor
THE EYE IS A CAMERA (the lens is the focusing element).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'глазная линза' in formal medical contexts; the standard term is 'хрусталик' (crystalline lens). 'Глазная линза' might be understood but sounds like a contact lens or an unnatural translation.
- Do not confuse with 'контактная линза' (contact lens).
Common Mistakes
- Misspelling as 'eyelens' (should be two words or hyphenated: 'eye-lens').
- Using it to mean 'eyeglasses' or 'contact lens'.
- Incorrect plural: 'eye lenses' is acceptable when referring to multiple lenses from multiple eyes, but 'lens of the eye' is often preferred.

Rarely and only in highly technical surgical jargon (e.g., 'to lens an eye'), meaning to fit or implant a lens. It is not standard English.
The 'crystalline lens' or simply 'the lens' (when context is clear).
This condition is called a cataract, often due to age-related changes in the proteins within the lens, causing it to lose transparency.
